Dinnerware with the Kovels

It is no longer deemed improper to mix and match china pieces. In fact, it lends charm to a dinner table and allows collectors to indulge in their passion while enjoying their pieces. Ralph and Terry Kovel, authors of "Kovels' Depression Glass and Dinnerware Price List," join Martha to share some popular collectible dinnerware patterns.

Cameoware: Made by Harker using the Engobe process, in which a stencil is used, resulting in a raised pattern.

Fiesta Ware: Fiesta was designed by Frederick Hurton Rhead in 1936 and is now among the most collected china products in the world. As originally designed, the line featured Art Deco styling and bold, bright colors. A turquoise onion soup bowl recently sold for $11,000.

Liberty Blue: Liberty Blue, made by Enoch Wedgwood, was a 1976 grocery store premium item issued to celebrate the United States's bicentennial. Its style is reminiscent of the nineteenth-century Staffordshire historical blue china.

Plaids Vernonware: Collectible California dinnerware made by Vernon Kilns in Vernon, California, from the 1940s to the 1950s. Available in rust, green, organdy, brown, and yellow.

Blue Ridge: Made by Southern Potteries of Erwin, Tennessee, between 1917 and 1947. Many patterns mix well because of similarities in designs and shapes.
